Gypsophila plant named ‘DGYPMILSII’

ABSTRACT

A new and distinct  Gypsophila  cultivar named ‘DGYPMILSII’ is disclosed, characterized by medium-small size, semi-double flower, with a diameter around 6 mm and a broad, open inflorescence. The new variety is a  Gypsophila , suitable for cut flower production and outdoor garden or container uses.

Latin name of the genus and species: Gypsophila paniculata.

Variety denomination: ‘DGYPMILSII’.

BACKGROUND OF THE INVENTION

The new Gypsophila cultivar is a product of chance discovery by the inventor, Gavriel Danziger. The new variety was discovered as a single plant seedling growing in a cut flower field of existing unnamed, unpatented Gypsophila paniculata varieties in Moshav Mishmar-Hashiva, Israel, in April 2013.

Asexual reproduction of the new cultivar ‘DGYPMILSII’ was first performed by basal vegetative cuttings during June of 2015, at a greenhouse in Moshav Mishmar-Hashiva, Israel. Subsequent propagation has shown that the unique features of this cultivar are stable and reproduced true to type in multiple successive generations.

SUMMARY OF THE INVENTION

The cultivar ‘DGYPMILSII’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, day length, and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘DGYPMILSII’ These characteristics in combination distinguish ‘DGYPMILSII’ as a new and distinct Gypsophila cultivar:

-   -   1. Medium-small flower diameter around 6 mm.     -   2. Semi-double flower.     -   3. Broad, open inflorescence structure.

PARENT COMPARISON

The new variety was discovered as a chance seedling among several unnamed Gypsophila.

COMMERCIAL COMPARISON

Plants of the new cultivar ‘DGYPMILSII’ can be compared to the commercial variety Gypsophila ‘DANGYPMINI’, U.S. Plant Pat. No. 10,964. The varieties are similar in most horticultural characteristics; however, ‘DGYPMILSII’ differs in the following:

-   -   1. The new variety has larger flowers than this comparator.

Plants of the new cultivar ‘DGYPMILSII’ can also be compared to the variety Gypsophila ‘DGYPCOSMIC’, U.S. Plant Pat. No. 29,525. These varieties are similar in most horticultural characteristics; however, ‘DGYPMILSII’ differs in the following:

-   -   1. The new variety has semi-double flowers, while this         comparator has full flowers.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photograph in FIG. 1 illustrates in full color a flowering stem of ‘DGYPMILSII’ grown outdoors in Moshav Mishmar-Hashiva, Israel.

FIG. 2 illustrates in full color a close up view of flowers of ‘DGYPMILSII’.

Plants in the photographs are approximately 4 months old. The photographs were taken using conventional techniques and although colors may appear different from actual colors due to light reflectance it is as accurate as possible by conventional photographic techniques.
